i want to do both eventually but i am dynoing in june and if i can only get one done by then, which will give the best reduction in egts? 3 piece exhaust manifold or tunnel ram and intake horn?

I vote exhaust manifold. Based on nothing but intuition and a hunch though:thumbsup:

Another vote for exhaust manifold.

I have both on my truck and noticed the biggest drop in EGT's with the Stainless Diesel Exhaust.

I vote tunnel ram. Drop EGTS and sooner spool up

The manifold will give you more of a reduction in EGTs.

if you want a cheaper easy install o for the tunnel ram, most people see between 75-150* drop. exhaust manifold will get the job done too.

Tunnel ram should do slightly better
